Ars Technica reported on November 12, 2026, that the exoplanet TOI-2535b has stopped transiting its host star, TOI-2535, making it disappear from observations. The change makes the planet seem to vanish from observations, and the outlet's fuller report gives researchers' suspected cause. TOI-2535b is a hot Jupiter-sized planet that TESS identified as orbiting the K dwarf TOI-2535 about every eight days, and it had been observed transiting for roughly seven years. Its transit timing shifted by as much as six hours, and its transits grew shorter until they stopped. Researchers suspect an unseen companion on a different orbital plane is responsible, and they say that companion would need to be extremely massive or on a highly eccentric orbit. Their modeling indicated it would be at least roughly Saturn-sized. Ars Technica noted that the change is the fastest inclination shift observed for an exoplanet orbiting a single star, and that it is unclear how the system reached its current state. The companion has not yet been detected, and a third planet cannot be ruled out.
